Recently, I was trying to get a laptop (that had no ethernet port) connected to an ethernet device. The device communicates via HTTP, and the laptop had Windows OS.
The device manufacturer's tech support suggested getting an off-the-shelf:
- USB-to-ethernet adapter
- HDMI-to-ethernet adapter
I have heard of using ethernet cable as HDMI extension cables, but I have never heard of an HDMI-to-ethernet adapter. My question was "does this actually exist?"
My questions are:
- Can one do network communications through a computer's HDMI port?
- If yes, does the HDMI port require certain specs?
Hdmi ports on desktops and laptops only send video and audio signals they cannot send data packets so you cannot share your internet connection.
Ethernet-enabled HDMI cables can then carry data transmissions from a main source to other IP-based home entertainment devices.
Only devices that feature HDMI Ethernet Channel functionality are able to take advantage of this new feature.
High Speed HDMI Cable with Ethernet - This cable type offers the same performance (1080p and greater resolutions) as the High Speed HDMI Cable, plus an additional, dedicated data channel, known as the HDMI Ethernet Channel (HEC), for device networking. HEC functionality is only available if both the source and sink devices are equipped with HEC functionality. HEC connected devices that include this feature can send and receive data via 100 Mb/sec Ethernet, making them instantly ready for any IP-based application.
